American Airlines announced yesterday an expansion to its in-flight Wi-Fi to more aircrafts. The service, branded “GoGo“, is now available on 100 of American’s MD-80 aircraft, with another 50 installations planned by the end of the year. The announcement coincides with GoGo’s launch anniversary – a year ago, AA was the first US airline to launch the GoGo service. Soon after, Delta Air Lines followed, along with Air Tran.
